5.Which of these is an example of the body where homeostasis is
maintained?
A. The pH level of urine drops, causing a crystal formation. This leads to blocking of
urine and urine infection
B. The pH level of blood drops due to excess amount of CO2. The brain sends signal to
the diaphragm to increase breathing in order to get rid of excess CO2
C. The excess amount of allergens in the air causes inflammation in the lungs. This
makes breathing difficult
O D. Pelvic floor dysfunction causes stool to dry out. This leads to constipation.
Answer:

Scientists collected samples of each group of flies. They placed some of the flies, together, in flasks with both apples and hawthorn
fruit. Other flasks contained either apple-eating flies or hawthorne-eating flies. Only the flies in the single fruit flasks mated and
produced offspring. To confirm their results, the scientists isolated flies from each group and put one of each into a flask with food.
Eventually the flies died
without mating. What conclusions apply to this situation? All BUT ONE could apply.
A)One fly species became two species via natural selection.
B)By eating different fruits, the flies changed genetically.
C)Over time, each group evolved different traits that aided in their survival.
D)Living in the ground and emerging a different times was a kind of
geographic isolation
Answer:
D, Gene flow had been reduced between flies that feed on different food.

Explain the peppered moth events in terms of natural selection
Answer:
Tutt suggested that the peppered moths were an example of natural selection. He recognized that the camouflage of the light moth no longer worked in the dark forest. Dark moths live longer in a dark forest, so they had more time to breed. All living things respond to natural selection.

¿Por qué consideras importante la medición de propiedades y/o fenómenos en las ciencias experimentales?
Answer:
una medición debe ser precisa y objetiva ya que sólo de este modo es posible reproducir el diseño experimental en condiciones controladas
Explanation:
Las ciencias experimentales son aquellas que realizan estudios en condiciones controladas (experimentos) con el objetivo de comprender el mundo natural que nos rodea. La medición juega un papel crucial en las ciencias experimentales ya que sólo una medición precisa y objetiva permite reproducir los resultados obtenidos en diferentes experimentos. De este modo, el proceso de cuantificar magnitudes está directamente asociado a la confiabilidad de los datos obtenidos en un experimento y consecuentemente también a la confiabilidad de las conclusiones derivadas de la aplicación del método científico experimental.

Which of these statements correctly describes one way that asexual and sexual reproduction are alike?
A. Both types of reproduction require two parents to produce offspring.
B. Both types of reproductions result in offspring that are identical to one parent.
C. Both types of reproduction enable genetic information to be passed from parent to offspring.
D. Both types of reproduction can occur in all organisms, depending on environmental conditions.
C. Both types of reproduction enable genetic information to be passed from parent to offspring.
It doesn't matter if the reproduction is sexual or asexual, because the offspring has the parent(s) dna and genetics either way.
The primary similarity between sexual and asexual reproduction is that they both have as their primary goal the generation of progeny into which genetic information is passed on, hence option c is correct.
What is the difference between asexual and sexual reproduction?Asexual reproduction only requires one organism to create more offspring that are identical to the parent and each other.
A male and female cell combine during sexual reproduction to create children that are genetically distinct from their parents.
Sexual reproduction needs both a male and a female organism, as opposed to asexual reproduction, which only includes one organism.
Therefore, the benefits of sexual reproduction include the offspring's genetic diversity, hence option c is correct.

Explain what genetic engineering is, and give real life examples (more than 1) of humans introducing a gene from one creature/plant into another creature/plant. Why did humans do this? Was it successful? Help me please this is due in around 3 hours
Answer:
Genetic Engineering also known as genetic modification are techniques used to transfer genes from the cells of a donor organism to those of a recipient.
One example is the formation of golden rice. 3 types of genes are added. Two come from daffodils and one from a bacterium, together forming beta-carotene, the chemical which give carrots their colour hence the name 'golden rice'. This is an advantage in LEDCs as beta-carotene is converted to vitamin A, which could save the eyesight of millions of children.
Another example are bananas. The genes that produce antigens to a certain disease are taken and transferred to bananas. The antigens contained in the banana will stimulate an immune response. This has successfully prevented diseases, and it will not be necessary to get needles stuck in you. This can be a very efficient method of preventing diseases in countries that has bananas as their main source of calories.

The bushes have alleles for blue and red berries. Bushes with both red and blue alleles make purple berries.
If the birds only like to eat blue berries, what is the selective pressure the birds are putting on the bushes?
For more plants to have red
berries.
For more plants to have purple
berries.
For more plants to have blue
berries.
Submit
Answer:For more plants to have blue berries
Explanation:
If the birds only like to eat blue berries in an environment with blue and red berries, the birds are putting selection pressure for more plants to have red berries.
Selection pressures are factors that act to boost or limit the organism's capacity to thrive in an environment. It could be biotic or abiotic.
The availability of purple berries in the environment is dependent on the mixing of both blue and red berry alleles.If birds keep picking on the blue berries, it means fewer blue berries would be available to mix with red berries in order to produce purple berries.Hence, fewer blue and purple berries would be available in the environment with time leaving only red berries to thrive.In other words, the continuous picking on blue berries by birds will only increase the availability of red berries with time.

Identify which kingdoms within Eukarya are known as decomposers, and which are capable of photosynthesis
Answer:
1.Fungi 2.plantae
Explanation:
Particularly in woods, fungi play a key role in decomposition. Some fungi, like mushrooms, have a plant-like appearance. However, fungus lack chlorophyll, a pigment that green plants employ to produce their own food using sunlight as fuel.
What is the similarity between plant and fungi kingdom?The ability of plants to produce their own sustenance makes this the most significant distinction between them and fungus.
As you probably already know, plants produce their own food using carbon dioxide, sunshine, and water.
Photosynthesis is the name given to this process. On the other hand, fungi are unable to produce their own nourishment.
Therefore, within eukarya fungi act as a decomposer and plant are capable of photosynthesis.
